Derartige Rändelwerkzeuge sind bereits bekannt, ein Beispiel ist im Deutschen Patent DE 790 092 gezeigt. Beim Stand der Technik erfolgt die gegenläufige, synchrone Einstellung von zwei Schwenkbolzen über eine Gewindespindel. Eine Fixierung der Drehlage der Schwenkbolzen erfolgt dabei dadurch, dass die Gewindespindel selbsthemmend ausgebildet ist.The invention relates to a knurling tool with at least one thumbwheel carrying tool head, which is adjustably mounted on a shaft. such Knurling tools are already known, an example being in German Patent DE 790 092 shown. In the prior art, the opposite, synchronous adjustment takes place of two pivot pins via a threaded spindle. A fixation of the rotational position of Pivot bolt takes place in that the threaded spindle self-locking is trained.
